scenarios when trying to implement custom trait for serializing enums with Serde in Rust
I'm stuck on something that should probably be simple... I'm confused about I'm having trouble implementing a custom trait for serializing enums using the `serde` library in Rust. I've defined an enum with several variants and I want to ensure that during serialization, specific variants are output as certain strings. However, I'm working with a compilation behavior that states `the trait bound 'MyEnum: serde::Serialize' is not satisfied`. Here's the code I've written so far: ```rust use serde::{Serialize, Serializer}; #[derive(Debug)] enum MyEnum { VariantOne, VariantTwo, VariantThree, } impl Serialize for MyEnum { fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::behavior> where S: Serializer, { let s = match self { MyEnum::VariantOne => "one", MyEnum::VariantTwo => "two", MyEnum::VariantThree => "three", }; serializer.serialize_str(s) } } fn main() { let my_enum = MyEnum::VariantOne; let serialized = serde_json::to_string(&my_enum); println!("Serialized: {}", serialized.unwrap()); } ``` I've ensured that I have the `serde` and `serde_json` crates in my `Cargo.toml` with versions `1.0` and `1.0`, respectively. It's puzzling because I thought implementing the `Serialize` trait on `MyEnum` would allow it to be serialized correctly. When I run this code, I get the behavior indicating that the `Serialize` trait is not implemented for `MyEnum`, despite my implementation. I also tried adding `#[serde(untagged)]` but that didn't seem to help. Any guidance on how to resolve this scenario would be greatly appreciated! My development environment is Ubuntu 22.04. I'm working on a service that needs to handle this. Has anyone else encountered this?
